SpotOn CCD-Position Sensing

SpotOn CCD-Position Sensing

A high-resolution optical beam positioning device with sub-micron resolution.

The application program is compatible with Windows 7/8/10 OS (32 & 64 bit). For custom integration, an SDK package software is offered as standard.

The system is capable of measuring up to 3 beams simultaneously, both CW and pulsed beams. Offering a wide range of spectral response, from deep UV, VIS and up to 1550nm. High accuracy measurement – less than 5um deviation edge-to-edge. It is a USB3.0 based device, with data exporting capabilities to another computer via RS232, data logging and detailed statistics, SDK control for integration in user application programs.

Ordering Information

The system comes with a camera, a set of 2X NG10 filters in housing, a mounting post, USB attachment, software on CD disk, carrying case.

  • SPOTCCD-VIS-USB: System with USB interface, camera for VIS range 350-1100nm
  • SPOTCCD-UV-USB: System with USB interface, camera for UV range 190-1100nm
  • SPOTCCD-IR1310-USB:System with USB interface, camera for 350-1310nm
  • SPOTCCD-IR1550-USB: System with USB interface, camera for IR range 1550±50nm

(*)Based on a standard CCD for VIS, coated with a phosphor coating, enabling capture of signals at the 1550±50nm range.
